Shellscript differ-r
यह शेलस्क्रिप्ट दो निर्देशिकाओं का एक पुनरावर्ती रूप प्रदर्शन कर सकता है लेकिन केवल (उनके संबंधित स्थानों में) फाइलों की तुलना करता है जो एक विशिष्ट फ़ाइल नाम या फ़ाइल स्वरूप से मेल खाते हैं।

$ ./differ-r
Usage: compare files in two directories including subdirectories
./differ-r <source-dir> <target-dir> <pattern>
Example: ./differ-r subdir-1 subdir-2 "*.txt"
चल रहा है differ-r:
निष्पादित diffकमांड लाइनें हरे रंग के पाठ और आउटपुट के साथ मुद्रित होती हैं, जब कोई मैच नहीं होता है तो डिफ़ॉल्ट पाठ (निम्नलिखित स्क्रीनशॉट में काले रंग पर सफेद) के साथ मुद्रित किया जाता है।

rsync फ़िल्टर के साथ
यदि आपको अंतर का वर्णन करते हुए कोई आउटपुट प्राप्त करने की आवश्यकता नहीं है, तो केवल यह जानें कि कौन सी फाइलें अलग हैं या गायब हैं (ताकि rsyncउन्हें कॉपी करना चाहें), आप निम्न कमांड लाइन का उपयोग कर सकते हैं।
rsync --filter="+ <pattern>" --filter="+ */" --filter="- *"--filter="- */" -avcn <source directory>/ <target directory>

यदि आप लाइनों और निर्देशिकाओं के बिना टिप्पणी के एक साफ उत्पादन चाहते हैं, तो आप grepइस तरह से उत्पादन कर सकते हैं ,
